The study was carried out with the objective of to evaluate the embryo survival after the embryo transfer to the uterine horn ipsilateral and contralateral to the corpus luteum (CL) in llamas. Fourtythree llamas recipient females, from 4 to 6 years old were randomly assigned in 4 groups: G1 (n=10): CL in right ovary and ipsilateral embryo transfer, G2 (n=10): CL in right ovary and contralateral transfer, G3 (n=15): CL in left ovary and ipsilateral transfer, and G4 (n=8): CL in left ovary and contralateral transfer. Ten llamas were used as embryo donors, they were synchronized with LH (1ml), then superovulated with 1000 UI eCG and induced to luteolysis with PGF2α; after that, all of them were mated. The same day of mating, the recipients were treated with LH, with the purpose of synchronization with donors. Seven days postmating, the uterine horns were flushed to recover, evaluate and transfer the embryos. The nonsurgical embryo transfer was used the same day with fresh embryos. The results of pregnancy rate were 60% (G1) and 75% (G3) in recipient females with ipsilateral embryo transfer right and left respectively. On the other hand, contralateral embryo transfer right and left were 30% (G2) and 25% (G4) respectively. However, the differences did not reach significance (p>0.05) between G1 with G2, G3 and G4. Furthermore, G2 not differ (p>0.05) from G4. Whereas, there is difference (p less 0.05) between G3 with G2 and G4. These results indicate that pregnancy rate is major in llamas when the embryo transfer was to the uterine horn ipsilateral to the CL in the left ovary.
